I130 Changed to I181 but not received any letter yet (60day)

[tarvirdi]

Dear Friends,
My sister who is a US citizen (Texas- Austin) filled me a petition as I-130 for relative sister in 20 June 2001.
To check My status I always checked egov.uscis.gov and searching my Recite No. Before 2 months ago it always showed my case as pending in California Center, but after then it's status changed To I-181 and processing in Texas center. What it means? Is it good news? If good, I think I should receive a letter.
I am living outside US and don't received any letter yet (after 60 day). How long should I wait?
What is next steps after receiving any mail? Is there any time limit?
I think, To get visa for entering US I should have an appointment with embassy in UAE. If I don't receive any letter can I follow up with embassy (My sister selected UAE as preferred embassy)?
My family (husband and 2 children) are mentioned as family in my filling form also. If I get visa or greencard, can my family get visa to enter US also?
Sorry for long questions?
Thanks
Susan
